HULL-BURNER.

Specification of Letters Patent.

Patented June 1, 1915..

Application filed Iviay 13, 1913. Serial No. 767,382.

To all whom it may concern Be it known that 1, WILLIAM V. SNEED, a citizen of the United States, residing at Vernon, in the county of Vilbarger and State of Texas, have invented certain new and useful Improvements in Hull-Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in hull burners for use particularly in connection with cotton gins, and has for its object to provide a device which may be attached to a furnace and which will cause the hulls to be forced into the furnace and burnt.

Another object of my invention is to pro vide a device of the above character which may be easily attached to the door of a furnace without in any way causing any inconvenience to the operator.

A still further object of my invention is to provide a door which may be constructed in such a manner that the chute may be easily attached and disconnected, if it is desired that the same remain inoperative.

Still another object of my invention is to provide a means whereby the chute may be attached to the door of a furnace and form a substantially air tight joint, thereby preventing the escape of smoke into the furnace room.

TVith the above and other objects in view, I will now proceed to describe my invention in the following specification and accompanying drawings, in which,

Figure 1 is a view in elevation of my improved hull burning device as it would appear when applied to a furnace; Fig. 2 is a longitudinal sectional View of my improved hull burner taken on line 2-2 of Fig. 1; Fig. 3 is a detail sectional view of the mechanism by which my improved hull burner is attached to the furnace taken on line 3-3 of Fig. 4;; Fig. 4 is a detail view in elevation of one of the doors showing my attaching mechanism applied thereto; Fig. 5 is a detail sectional view of the ring by means of which the device is attached; Fig. 6 is a view of the plate which I place in position to close the opening through the furnace door when it is desired to use the furnace without the hull burner; Fig. 7 is, a detail view of the attaching means by which the injector is secured to the hull burner and Fig. 8 is a fragmentary perspective view of the lower section of the conveyer tube.

Reference being had more particularly to the drawings, 1 indicates the usual furnace structure provided with the boiler 2, the fire box 3, and the doors 4%. The usual ash pit 5 is positioned beneath the fire box, and access is gained thereto by means of the doors 6. A suitable smoke pipe 7 is provided at the top of the furnace and is adapted to communicate with a suitable stack or flue, through which the products of combustion are conducted to the outer surrounding atmosphere.

One of the doors 4 is provided with an aperture having a collar 8 secured therein. This collaris provided at its outer extremity with the laterally extending flange 9, by means of which a revoluble ring is held in position on the door. This ring, indicated by the numeral 10, is provided at one edge with the inturned flange 11, this inturned flange 11 being adapted to overlie the flange 9 on the collar 8 and thereby hold the ring 10 in position on the collar. A second inturned flange 12 is provided at the 0pp0- site side of the ring, and its inner face is preferably tapered, as clearly illustrated at 13 in Fig. 5, to form a cam surface, the use of which will be more fully hereinafter described. Suitable handles 14 are formed 1ntegrally with the ring at diametrically 0pposite points, by means of which said ring is adapted to be rotated. The flange 12 of the ring is preferably cut away, as illus trated at 15, to receive a flange formed on the end of the conveyer tube.

A suitable conveyer tube 16 extends up wardly from the furnace and communicates at its upper extremity with a tubular conveyer, indicated generally at 17 this tubular conveyer being adapted to carry the hulls from the gin to the conveyer tube 16, where the said hulls are fed into the conveyer tube and downwardly into the furnace. The lower extremity of the tube 16 is provided with a suitable elbow joint 18,

by means of which the lower section 19 of the conveyer tube, carrying the elbow 20, is hingedly secured to the tube 16. The terminal of the elbow 20 is provided with the laterally extending annular flange 21,

which is cut away in a manner similar to 3- that indicated by 15 on the ring 10, so that the said flange may pass through the opennicates with the boiler and is provided adsection 25 to the supply pipe 22.

jacent one extremity with a valve 23, by means of which the flow of steam is regulated. A suitable elbow joint 24 is provided and is adapted to connect the lower This lower section 25 is provided at its lower extremity with an angular extension 26, which tapers toward its terminal and enters the elbow 20 formed on the section 19. Thus it will be seen that when steam is admitted to the pipe 22 through the valve 23 and into the extension 25, said steam will pass through the laterally extending portion 26 and into the interior of the elbow 20, from whence it will pass into the fire box 3 and over the coal.

A suitable plate 27 is provided with a handle 28, and has formed integral therewith the dove-tailed portions 29 which are adapted to pass through the recess 15 formed in the flange 12 in order that, when it is desired to eliminate the use of the hull burner, the opening through the furnace door may be closed by the insertion of the plate 27.

The flow of the hulls through the tube 16 is controlled by means of the valve 30 located intermediate the conveyer and the lower extremity of the tube. Thus it will be seen that by the manipulation of said valve the flow of the hulls may be at all times under the control of the operator.

A suitable band 31 surrounds the lower section 19 of the conveyer tube and is adapted to detachably secure the extension 25 of the injector to the said lower section 19. This injector is surrounded by an extension formed on the collar which is held in place by means of a bolt and wing nut 32. Thus it will be seen that when it is so desired the injector may be thrown out of position and the conveyer tube disconnected from the furnace.

In operation the hulls are carried from the gin by means of the conveyer 17, from which they pass into the conveyer tube 16, thence downwardly through the elbow joint 18' and into the lower section 19, which terminates in the elbow 20. Steam is then admitted into the injector which, upon passing through the elbow 20 and into the fur- G'opies of this patent may be obtained for nace, forces the hulls into said furnace and over the fire, so that they may be burnt. When it is desired to use the furnace without the hull burning attachment, the steam is cut off and the valve 30 closed. The thumb nut is then released from the bolt and the injector tube 25 swung upwardly from the elbow joint 24 to a horizontal position. Upon revolving the ring 10 in order that the cut away portions 15 will register with the flange 21, the lower section 19 of the tube may be swung upwardly into a horizontal position so that it will be out of the way of the furnace door. The plate 27 is then inserted beneath the ring and the said ring revolved, thereby holding the plate firmly in place and closing the opening through the door.

While in the foregoing I have shown and described the preferred embodiment of my invention, I wish it to be understood that I may change the specific arrangements of parts without in any way departing from the spirit and scope of my invention.

Having thus fully described my invention what I claim is:

A furnace door comprising a body having a central aperture therein, a collar formed on the door adjacent to the aperture and surrounding the same, an outwardly extending flange formed at the free edge of the collar, a ring surrounding the periphery of the flange, an inwardly extending flange formed on the ring and arranged to engage the outwardly extending flange to retain the ring in position on the collar, a second inturned flange on the ring, the second flange being on the end of the ring opposite to the first mentioned inwardly extending flange, the second inturned flange being partially cut away to form openings, a conveyer tube, an outwardly extending flange on the conveyer tube, said flange being cut away so that the same will pass through the openings formed in the second inturned flange, and a plate arranged to be substituted to close the aperture in the door when the conveyer tube is not in use.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM VERNON SNEED.
